Two resistors or resistance 2ohms and 4 ohms are connected in series and then in parallel what is the ratio of their
respective resistance

Ratio = 9 : 2

Explanation:

We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.

First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:

Resistance (Equivalent) = R₁ + R₂ = 6 ohms

When these are connected in parallel, equivalent resistance becomes:

1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4

1 / Resistance (Equivalent) = 3/4

Resistance (Equivalent) = 4/3

Ratio = R(Series)/ R(Parallel)

Ratio = 6 : 4/3

Ratio = 18 : 4

Ratio = 9:2

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
